Hi @Sixiao -- the name comes from the PCI domain number from the script and name suggested earlier (in the sample instance, and bug #1695119 if you have access to it). It's really of no special interest to cloud-init which it is. Renaming to vf0 would be a separate change/SRU, please file that as a separate bug if that is how you would like it to behave on Azure.
